it’s a common requirement to create a report that shows last N days of a business metric – so I thought I’ll post a template here for SQL server analysis server’s MDX query:
MEMBER [Measures].[Sales_last_15_days] AS
MEMBER [Measures].[CurrDate] as
"[Calendar].[Date YYYYMMDD].[" + Cstr(Year(Now())*10000+month(now())*100+day(now())) +"]"
} ON COLUMNS
Here are things that you’ll need to adjust to make it work for your scenario:
1. Date Dimension Attribute & it’s format. The example shows yyyymmdd but you could have different format of the date.
2. Measure name. Instead of [Measures].[Sales] you’ll have to replace it with your business metric. Also, make sure you are using the right aggregate function, in the example above I have used SUM but you’ll have to change this based on your requirement.
3. Create a parameter and use it in index for the Lag function.
4. change [cubename] to your cube name.
I hope this gives you a good starting point to create last N days for your business metric.
Setting the default value for parameters like today’s date & current month is great because that way consumer do not need to manually input the parameter value. I was working on a requirement to pass previous day to the date parameter.
So here’s the quick tip to set the default value of the date parameter to previous day.
Part 2/2 of the series on building Ideal Models for Power View reports is live!
Summary: “In this article, we will first compare the PowerPivot and Tabular models, which will help you choose between these two models for your scenarios, and then we will study the reporting properties in a Tabular Model that you can configure to build an Ideal model for Power View reports.”

My journal article titled “Building Ideal PowerPivot Model for Power View reports” got published in SolidQ Journal. In this article, I talk about reporting properties in PowerPivot Model that you can set which will enhance the Power View report creation experience of your end-users. Here are the five main topics discussed in the article:
– Hide from Client Tools
– Default Field Set
– Table Behavior
– Calculate Columns and Calculate measures
In the Part 2 of this series, we will discuss the reporting properties in Tabular Model to help you build an ideal Model for Power View reports.
I’ll let you know when that’s published Part 2 is Published: http://parasdoshi.com/2012/09/25/new-journal-article-published-title-building-an-ideal-tabular-model-for-power-view-reports/
I would also like to thank the SolidQ Journal Team and Ruben Lopez who was the Technical reviewer of the article.
